[0036] Example 1

[0037] See Figure 2 An embodiment of the present invention provides a printing device with an ink absorbing function, the printing device comprising:

[0038] The object carrier component 3 is used to place the three-dimensional substrate 4 to be printed;

[0039] The ink absorbing components 1 are arranged around the three-dimensional printing substrate 4. Each ink absorbing component 1 is adjacent to one side of the three-dimensional printing substrate 4. The ink absorbing component 1 is provided with an ink absorbing port 17 on the side close to the three-dimensional printing substrate 4. Ink enters the ink absorbing component 1 through the ink absorbing port 17.

[0040] Specifically, the loading component 3 can be a loading platform or a clamping member for placing the three-dimensional printing substrate 4. If necessary, the three-dimensional printing substrate 4 can be fixed to a certain extent to prevent the airflow driven by the ink absorption component 1 from affecting the position of the printing substrate and affecting the positioning accuracy of the printing when it is in operation.

[0041] The ink absorbing component 1 is a three-dimensional structure as a whole, and the ink absorbing port 17 is long and narrow, which can completely collect the ink at the edge of the three-dimensional printing material 4.

[0042] Generally, the number of sides of a three-dimensional printing substrate 4 is the same as the number of ink-absorbing components 1 provided. For example, when the three-dimensional printing substrate 4 has four sides, four sets of ink-absorbing components 1 need to be provided accordingly. When the three-dimensional printing substrate 4 has six sides, six sets of ink-absorbing components 1 need to be provided accordingly.

[0043] The printing device with ink absorption function provided in this embodiment clamps the three-dimensional printing substrate 4 through the carrier component 3 or places the three-dimensional printing substrate 4 on the carrier component 3 for fixed placement, and multiple groups of ink absorption components 1 are placed around the three-dimensional printing substrate 4. During inkjet printing, the ink absorption component 1 drives the air flow to take away the jet-printed ink from the ink absorption port 17, thereby avoiding ink accumulation on the printing device or the clamping device to affect the positioning and printing quality of subsequent substrates.

[0044] In one embodiment, if Figure 3-Figure 5 As shown, the two adjacently arranged ink absorbing components 1 are arranged in a height-staggered manner in a direction perpendicular to the surface of the printing substrate.

[0045] Specifically, such as Figure 3 、 Figure 4 As shown, the first ink absorbing assembly 12 and the second ink absorbing assembly 13 are arranged in a staggered manner to avoid ink loss in the corner areas formed by the two corrugated edges of the substrate.

[0046] In one embodiment, if Figure 6-Figure 9 As shown, the ink absorbing assembly 1 includes an inner cavity 14, a top plate 15 and an outward protruding plate 16 on one side of the three-dimensional printing substrate 4. The ink absorbing port 17 is formed between the outward protruding plate 16 and the top plate 15. A gap 18 is set between the outward protruding plate 16 and the three-dimensional printing substrate 4.

[0047] Specifically, an ink suction port 17 is formed between the outward protruding plate 16 and the top plate 15, and the ink suction port 17 faces the edge of the surface of the substrate; the ink suction port 17 is connected to the inner cavity 14. During operation, the flowing air will cause the ink printed or about to be printed on the printing device / clamping member or the edge of the surface of the substrate to flow from the ink suction port 17 into the cavity.

[0048] At the same time, the gap 18 between the outward protruding plate 16 and the three-dimensional substrate 4 is preferably 0.5mm-3mm, ensuring that there is a certain gap between the ink suction port 17 and the substrate, allowing air to circulate smoothly and avoiding the ink from not being able to be sucked into the inner cavity in time due to poor air flow.

[0049] Preferably, the ink absorbing assembly 1 includes a main body 19 , a top plate 15 , an outwardly protruding plate 16 close to the side of the three-dimensional printing object 4 , a detachable first side plate 110 , and a second side plate 111 opposite to the first side plate 110 .

[0050] A cavity, namely the inner cavity 14 , is formed in the main body 19 , and the ink flowing in from the ink suction port 17 is collected in the inner cavity.

[0051] The outward protruding plate 16 is detachably mounted on the main body 19 , and the mounting position of the outward protruding plate 16 on the main body 19 can be adjusted according to the height of the three-dimensional printing substrate 4 to meet the ink collection requirements of three-dimensional printing substrates 4 of different heights.

[0052] Preferably, the ink absorption component also includes an ink receiving groove 112, which is arranged below the outward protruding plate 16. When the splashed ink fails to flow from the ink absorption port 17 to the inner cavity 14 but falls from the gap 18 between the outward protruding plate 16 and the three-dimensional printing material, it is received by the ink receiving groove 112 from the ink receiving port 1121 and flows from the ink outlet 1122 into the inner cavity 14.

[0053] In one embodiment, if Figure 9 As shown, the ink absorbing assembly 1 includes an ink collecting tank 7 arranged in the inner cavity 14 for collecting ink.

[0054] Specifically, the ink collecting bin 7 is movably installed in the inner cavity 14 for collecting the ink flowing into the cavity. When the ink is collected to a certain extent, the ink collecting bin 7 is taken out through the detachable first side plate 110 or the second side plate 111 .

[0055] In one embodiment, the ink absorbing assembly 1 includes an ink absorbing member for absorbing ink.

[0056] Specifically, the ink absorbing member is a component that can absorb ink, such as a sponge or other component that can absorb liquid.

[0057] In one embodiment, the printing device further includes an air extraction component (not shown) for extracting air from the inner cavity 14 .

[0058] Specifically, such as Figure 10 As shown, the gas in the ink absorbing component 1 is extracted through the vacuum component, so that the air pressure in the cavity of the ink absorbing component 1 is reduced, and the outside air flows into the cavity of the ink absorbing component 1 through the ink suction port 17, and the gas in the cavity is extracted to the outside through the vacuum component to realize the flow of gas.

[0059] In one embodiment, if Figure 2 and Figure 3As shown, the printing device also includes a gas diversion component, which includes a main control unit 22 and a sub-control unit (not shown in the figure). One end of the sub-control unit is connected to the main control unit 22, and the other end is connected to the air inlet 11 of the ink suction component 1. The main control unit 2 is connected to the air suction component.

[0060] Specifically, the main control unit 2 is set on one side of the carrier component 3, and the sub-control unit is connected to the air inlet 11 of the ink absorption component 1 to circulate the air in the ink absorption component 1 to the main control unit 2. The main control unit 2 is connected to the exhaust component to discharge the gas in the main control unit 2 to the outside.

[0061] Preferably, the sub-control unit adopts a catheter.

[0062] In inkjet printing operations, it is impossible to spray ink onto the surface of the substrate simultaneously. In this embodiment, the sub-control units and the main control unit 2 can control the ink absorption of each ink absorption component 1 to avoid waste of resources.

[0063] In one embodiment, a filter unit (not shown) is provided in the master control unit 2 for filtering flying ink in the gas.

[0064] The ink flows along with the gas from the ink suction port 17 into the inner cavity of the ink suction component 1 and is collected. Some ink still flows along with the gas through the air inlet 11 and the sub-control unit to the main control unit 2. In order to prevent the flying ink from flowing into the external environment and causing pollution, a filter unit is set in the main control unit 2 to filter the ink in the gas to avoid environmental pollution.

[0065] The printing device with ink absorption function provided in this embodiment clamps a three-dimensional printing substrate 4 with a carrier assembly 3 or places the three-dimensional printing substrate 4 on the carrier assembly 3 for fixed placement. Multiple sets of ink absorption assemblies 1 are placed around the three-dimensional printing substrate 4. An air extraction assembly is also provided to extract the gas within the ink absorption assemblies 1. During inkjet printing, the air extraction assembly extracts the gas from the inner cavity 14 of the ink absorption assembly 1, driving external air into the ink absorption assembly 1 through the ink absorption port 17. At the same time, it also brings excess ink into the ink absorption assembly 1 for collection. This prevents ink from accumulating in the printing device or the clamping device, causing subsequent positioning of the substrate.

[0066] Example 2

[0067] See also Figure 11 , an embodiment of the present invention provides a printing device, the printing device comprising:

[0068] The printing device with ink absorption function as described in the above embodiment 1;

[0069] A working platform 6, used for placing the printing device;

[0070] The inkjet printing assembly 5 is installed above the working platform and is used for performing inkjet printing on the three-dimensional printing material on the object-carrying assembly.

[0071] In one embodiment, if Figure 11 As shown, the printing assembly is movably installed above the working platform and is used to perform inkjet printing on the three-dimensional printing material on the printing device during the movement.

[0072] Specifically, the inkjet printing assembly performs scanning and printing along the X direction, and steps along the Y direction to perform inkjet printing on the next printing area.

[0073] In one embodiment, if Figure 11 As shown, the printing assembly is fixedly installed above the working platform. The movement of the working platform drives the printing device to move, and the printing assembly performs inkjet printing on the three-dimensional printing material moved below.

[0074] Specifically, the inkjet printing assembly scans and prints along the X direction, controls the working platform to move in steps in the Y direction, drives the printing device and the substrate to move relative to the inkjet printing assembly in the Y direction to perform inkjet printing on the next printing area.

[0075] This embodiment provides a printing device with an ink-absorbing function. The printing device clamps a three-dimensional printing substrate with a carrier assembly or places the three-dimensional printing substrate on a carrier assembly for fixed placement. Multiple sets of ink-absorbing assemblies are placed around the three-dimensional printing substrate, and an air extraction assembly is provided to extract the air within the ink-absorbing assemblies. During inkjet printing, the air extraction assembly extracts the air from the inner cavity of the ink-absorbing assembly, driving external air into the ink-absorbing assembly through the ink-absorbing port. Excess ink is also drawn into the ink-absorbing assembly for collection. This prevents ink from accumulating in the printing device or the clamping device, causing subsequent positioning of the substrate.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
